Medication
The main symptom of supraventricular tachycardia (SVT) is a very fast heartbeat (100 beats a minute or more) that may last for a few minutes to a few days. The fast heartbeat may come and go suddenly, with stretches of normal heart rates in between. Some people with SVT have no signs or symptoms at all.
Procedures
SVT is also called paroxysmal supraventricular tachycardia. A normal heart rate is 60 to 100 beats per minute. A heart rate of more than 100 beats per minute is called a tachycardia (tak-ih-KAHR-dee-uh).
Therapy
Paroxysmal supraventricular tachycardia (PSVT):Now and then, electrical signals going from the upper to the lower chambers create more heartbeats than you need. This can happen with Wolff-Parkinson-White Syndrome(WPW). You can have more than 100 (and sometimes more than 250) beats a minute with PSVT. Ventricular arrhythmias
Nutrition
During an episode of SVT, your heart beats about 150 to 220 times per minute, but it can occasionally beat faster or slower. Most people with supraventricular tachycardia live healthy lives without restrictions or treatment.

How long does paroxysmal supraventricular tachycardia last?
The main symptom of supraventricular tachycardia (SVT) is a very fast heartbeat (100 beats a minute or more) that may last for a few minutes to a few days. The fast heartbeat may come and go suddenly, with stretches of typical heart rates in between.
Is PSVT a serious heart condition?
PSVT is generally not life threatening. If other heart disorders are present, it can lead to congestive heart failure or angina.
Can SVT go away over time?
SVT can go away on its own, with medication, or with certain actions used to slow heart rate: holding your breath, coughing, or immersing your face in cold water.
Can supraventricular tachycardia be temporary?
Supraventricular tachycardia (SVT) is a heart condition featuring episodes of an abnormally fast heart rate. The heart will suddenly start racing, then stop racing or slow down abruptly. Episodes can last for seconds, minutes, hours or (in rare cases) days.
Can you get rid of supraventricular tachycardia?
Many people with SVT have a procedure called catheter ablation. This procedure can stop the rhythm problem in most people. During this procedure, the extra electrical pathway or cells in the heart that are causing the fast heart rate can often be identified and destroyed. Ablation is considered safe.
Is SVT a permanent condition?
The abnormal heartbeat may last for a few seconds to a few hours before your heart returns to its normal rhythm. Some SVT rhythms can last for days or weeks, or even become permanent.
What triggers PSVT?
PSVT (also called re-entry tachycardia) is a type of atrial arrhythmia. It happens when there is abnormal electrical activity in the atria. This is caused by an abnormally irritable area in the atria or by a short circuit in your heart causing electrical signals to travel around and around in a circular pattern.
Can you live a long life with SVT?
In the vast majority of cases SVT is a benign condition. This means that it will not cause sudden death, damage the heart or cause a heart attack. It will not shorten life expectancy.
Can SVT be caused by anxiety?
If you are worn out or anxious, you may be more likely to have a bout of SVT. One small study was able to record electrical changes in the hearts of people with the condition who were mentally stressed. Another study concluded that panic attacks can trigger this.
Can tachycardia heal itself?
Tachycardia is often harmless and goes away on its own. However, if your heartbeat won't return to normal, you need to visit the hospital. Overworking your heart for too long can lead to a heart attack, stroke, or other cardiovascular problem.
What causes SVT to develop?
SVT is often caused by faulty electrical signaling in your heart. It's often brought on by premature beats. Some types of SVT run in families, so genes may play a role. Other types may be caused by lung problems.
Can you exercise with PSVT?
Exercise Safely Just be more careful about fitness. Check with your doctor to see how much exercise and which types are safest for you. You may need a stress test to find out how much activity you can handle. Start any new exercise program slowly.
Does SVT damage the heart?
In the vast majority of cases SVT is a benign condition. This means that it will not cause sudden death, will not damage the heart or cause a heart attack and will not shorten life expectancy.
Can PSVT cause heart failure?
While PSVT usually does not threaten your life if you have it, it can lead to congestive heart failure or angina if you have other heart problems. PSVT is caused by extra electrical pathways between the heart's upper chambers (atria) and lower chambers (ventricles).
What is the best medication for supraventricular tachycardia?
Commonly prescribed medications are beta-blockers, verapamil, and digoxin. Occasionally, other medications called antiarrhythmic drugs (such as amiodarone or sotalol) may be given to prevent SVT episodes from occurring.
How do you avoid SVT episodes?
Lifestyle changes to help prevent SVT episodesHave less alcohol and caffeine.Don't smoke.Lower your stress.Eat foods that are healthy for your heart.Don't take recreational drugs, especially stimulants that can over-excite the heart muscle. ... Stay well hydrated and get enough sleep.
How do I get my heart back in rhythm naturally?
Exercise can improve overall cardiovascular health and help restore the heart's natural rhythm. It can also help reduce stress and anxiety. Cardiovascular exercise helps strengthen the heart, which can prevent or reduce palpitations....Exercise regularlybrisk walking.jogging.running.biking.swimming.
How long is too long for tachycardia?
If it lasts more than a few minutes, call 911 or your doctor.
Does SVT run in families?
SVT is usually a result of faulty electrical signaling in your heart. It is commonly brought on by premature beats. Some types of SVT run in families, so genetic differences may play a role.
Can SVT turn into AFIB?
Conclusions: This study suggests that atrial fibrillation will develop in approximately 12% of patients with paroxysmal supraventricular tachycardia during a 1-year follow-up period. The occurrence of atrial fibrillation is not related to the mechanism or heart rate of the paroxysmal supraventricular tachycardia.
Can PSVT cause heart failure?
While PSVT usually does not threaten your life if you have it, it can lead to congestive heart failure or angina if you have other heart problems. PSVT is caused by extra electrical pathways between the heart's upper chambers (atria) and lower chambers (ventricles).
What is the drug of choice for PSVT?
Verapamil is considered by many investigators to be the drug of choice for the acute management of uncomplicated PSVT. Several clinical investigators have demonstrated termination of PSVT in more than 90% of their patients within minutes following IV drug administration.
Can PSVT cause stroke?
Paroxysmal supraventricular tachycardia (PSVT) has been traditionally considered as a benign rhythm disorder. However, recent studies have suggested that patients with PSVT may have a higher risk of ischemic stroke although the data are limited and inconclusive.
Can you exercise with PSVT?
Exercise Safely Just be more careful about fitness. Check with your doctor to see how much exercise and which types are safest for you. You may need a stress test to find out how much activity you can handle. Start any new exercise program slowly.

Why do you need an EPS for PSVT?
An electrophysiology study (EPS) may be needed for an accurate diagnosis and to find the best treatment. Because PSVT comes and goes, to diagnose it people may need to wear a 24-hour Holter monitor. For longer periods of time, another tape of the rhythm recording device may be used.
What is the electrical signal that causes the heart to contract?
The contractions are caused by an electrical signal that begins in an area of the heart called the sinoatrial node (also called the sinus node or SA node). The signal moves through the upper heart chambers (the atria) and tells the atria to contract.
What is the treatment for a repeat heartbeat?
Long-term treatment for people who have repeat episodes of PSVT, or who also have heart disease, may include: Cardiac ablation, a procedure used to destroy small areas in your heart that may be causing the rapid heartbeat (currently the treatment of choice for most PSVTs) Daily medicines to prevent repeat episodes.
